| Abstract: | The dispersant of acrylic acid-styrene sulfonic sodium-3-hydroxypropyl acrylate copolymer was synthesized with acrylic acid,styrene sulfonic sodium and 3-hydroxypropyl acrylate as monomers and tested as dispersants for the aqueous dispersion of TiO2 granules.At the same time,SEM and laser diffraction particle size analyzer were applied to analyze the properties of suspensions.With the help of the dispersant synthesized herein,well-dispersed suspensions of TiO2 could be achieved,and the suspension percentage... |
